Wilksbarre, PA -- from here, set destination as "Bath, NY'' to force a NW heading/drive. Settings in Maps: "Avoid highways; Avoid tolls"
Routes should hug the Susquehanna. Take the '5 minutes longer' grey options when GMaps offers these options. Get lost. Or don't avoid the highway and take 6, which can be incredibly high-speed, and you will have pickup truck drivers that will run off the mountain to prove they can hang. All along this run up along the Susquehanna, I am hard pressed to remember more adrenaline getting dumped into my blood stream. Did it in the 4C.
South and West of Philly, in Chester County -- from here, find routes, 841, 82, 53, 896, 842 and get lost. Leave setting as 'Avoid Highways; Avoid tolls. Pick random destinations.

Pertains to all the above: Do not under any circumstances drive these roads at 10/10ths unless you've memorized them. You will encounter tightening radius turns (decreasing radius), so if you apex at max grip, and you encounter a decreasing radius, you're going off the road, down the mountain, into opposite traffic or into a tree -- no questions asked.
